Title: Overvoltage protection method and semiconductor device employing the method
Inventor: KAWAGOE HIROKAZU
IPC: H01L27/06
Filed: 1992-11-30
Abstract: PURPOSE:To protect an output transistor from an overcurrent concentration breakdown caused by an overvoltage applied to the output transistor with a simple construction by a method wherein a diode whose breakdown voltage is lower than the breakdown voltage of the output transistor is formed between the drain and source of the output transistor. CONSTITUTION:A vertical MOS-FET is formed on an N-type substrate 4 as an output transistor 1a. A protective diode 2a whose breakdown voltage is lower than the breakdown voltage of the output transistor 1a and an N-type channel MOS-FET which is a GS clamping transistor 3a which has an insulating oxide film 10a as a gate oxide film are formed around the output transistor 1a. If an overvoltage is applied to a drain terminal 12a while a voltage for driving the output transistor is applied to a gate terminal 13a, the GS clamping transistor 3a is turned on and the potential of the gate terminal 13a is directly applied to a source and the energy produced by the overvoltage is concentrated on the protective diode, so that the output transistor la can be protected.

Filed: 1989-12-08
Abstract: PURPOSE:To surely restore the original picture from an obtained digital picture by regarding 2-dimension picture information as convolution of a point spread function whose variable is separated from picture information and decoding the function algebraicly by a matrix equation.
